I've updated the BIOS to 2.30, so that now my dmesg shows:
[ 20.346577] thinkpad_acpi: ThinkPad ACPI Extras v0.25
[ 20.346580] thinkpad_acpi: http://ibm-acpi.sf.net/
[ 20.346582] thinkpad_acpi: ThinkPad BIOS 7LETD0WW (2.30 ), EC 7KHT24WW-1.08
[ 20.346583] thinkpad_acpi: Lenovo ThinkPad T61p

Ubuntu 16.04 (Dev branch) x64 and I confirm that the bug is still there
(same machine as in the original problem report).
